Flutter - Get Device Language (Locale) Examples
If you develop an application, you may need to detect what is the language or locale used by the device. Especially if the application supports multi-language. By doing so, the application can automatically use the most suitable locale according to the device. This tutorial includes how to enable localization in a Flutter application, how to get the language code and locale code, as well as how to detect locale change.
Flutter has a Locale class by which you can get the country code and language code (such as en-US, en-UK, es-ES). It's possible to get the current locale from the BuildContext. However, a Flutter application only supports English (United States) (en-US) locale by default. Therefore, even if the device uses another language, if the device language is not supported by the Flutter application, you'll get the default locale which is en-US.
As a result, you need to make the Flutter application supports localization and set the list of allowed locales. First of all, add flutter_localizations to the pubspec.yaml file, right under the dependencies key.
